A facile multicomponent, catalyst-free oxazolidinone synthesis from primary aliphatic or aromatic amines and dibromoethane is described. It relies on the usage of cesium carbonate or cesium hydrogencarbonate as the simultaneous base and C1 source, furnishing a broad scope with high yields, including the synthesis of an oxazolidinone-modified dipeptidyl peptidase 8 inhibitor.
